“…Finally, the problem still exists of what to do with the secondary or tertiary drainage water that will be generated from water reuse systems. Rhoades and Dinar (1991) have demonstrated the negative impacts of returning this drainage water to potential water delivery systems (Table 1). Several methods exist, including evaporation ponds and deep-aquifer injection, that can serve as temporary solutions.…”

“…Strategy 3 is similar to Strategy 2, except that drainage from the cotton is not returned to the river (assumes on-farm disposal) y Unitless parameters. They apply to any volume measured in the model (Rhoades and Dinar, 1991). salinity increased the sugar content of cantaloupe (Cucumis melo L.) as much as 2%.…”

“…In Adelaide, Australia, water from the Murray-Darling watershed, after use and reuse along its course, arrives in Adelaide at salt concentrations exceeding those of sea water (Ghassemi et al, 1995). Rhoades and Dinar (1991) provided conceptual and empirical evidence to show how water use on hypothetical farming systems along a river can diminish water quality for downstream users. The model that they developed tested the advantages and disadvantages of three options for water use.…”

“…However, such a conclusion may not be justifi ed based solely on one observation. Since cowpea is grown in the southern San Joaquin Valley of California (Hall and Frate, 1996), a more defi nitive growth response study comparing high-sulfate solutions, typical of drainage waters in the San Joaquin Valley (Deveral, et al, 1984), with high-chloride waters would be useful in determining if cowpea may be used in a drainage water reuse program in the San Joaquin Valley (Rhoades and Dinar, 1991).…”

Over the last several years, there has been increasing interest in amending the soil using cover crops, especially in desert agriculture. One cover crop of interest in the desert Coachella Valley of California is cowpea [Vigna unguiculata (L.) Walp.]. Cowpea is particularly useful in that as an excellent cover crop, fi xing abundant amounts of nitrogen which can reduce fertilizer costs. However, soil salinity problems are of increasing concern in the Coachella Valley of California where the Colorado River water is a major source of irrigation water. Unfortunately, little information is available on the response of cowpea growth to salt stress. Thus, we investigated the growth response of 12 major cowpea cultivars ('CB5', 'CB27', 'CB46', 'IT89KD-288', 'IT93K-503-1', 'Iron Clay', 'Speckled Purple Hall', 'UCR 134', 'UCR 671', 'UCR 730', '8517', and '7964') to increasing salinity levels. The experiment was set up as a standard Split Plot design. Seven salinity levels ranging from 2.6 to 20.1 dS·m -1 were constructed, based on Colorado River water salt composition, to have NaCl, CaCl2 and MgSO4 as the salinization salts. The osmotic potential ranged from -0.075 to -0.82 MPa. Salt stress began 7 days after planting by adding the salts into irrigating nutrient solution and ended after 5 consecutive days. The plants were harvested during fl owering period for biomass measurement (53 days after planting). Data analysis using SAS analysis of variance indicated that the salinity in the range between 2.6 and 20.1 dS·m -1 signifi cantly reduced leaf area, leaf dry weight, stem dry weight and root dry weight (P ≤ 0.05). We applied the data to a salt-tolerance model, log(Y) = a 1 + a 2 X + a 3 X 2 , where Y represents biomass, a 1 , a 2 and a 3 are empirical constants, and X represents salinity, and found that the model accounted for 99%, 97%, 96%, 99%, and 96% of salt effect for cowpea shoot, leaf area, leaf dry weight, stem dry weight and root dry weight, respectively. We also found signifi cant differences (P ≤ 0.05) of each biomass parameter among the 12 cultivars and obtained different sets of the empirical constants to quantitatively describe the response of each biomass parameter to salinity for individual cowpea cultivars. Since a signifi cant salt × cultivar interaction effect (P ≤ 0.05) was found on leaf area and leaf dry weight, we concluded that salt tolerance differences exist among the tested cultivars.

“…For the most part to date, countries have attempted to solve scarcity problems by domestic means. Options on i e supply side include reuse of sewage effluent, use of marginal floodwater and saline sources, seawater desalination, cloud seeding, internal transfer of water SU 1 itlus, and separation of drinking water from irrigation and industrial water permitting use of recycled waste water in the latter uses (Rhoades and Dinar 1991). All of these options are either expensive or have an uncertain payoff.…”

The problem of water scarcity has become more acute in many regions of the world because of economic and population growth and because of degradation of historic water resources. New resources and more efficient use of old ones are needed, but large investments and effective institutions are needed for allocating water, monitoring its use, and ensuring its quality. Because most economically feasible but yet undeveloped water projects involve water drawn from and used by multiple jurisdictions, regional or international cooperation is required. This paper develops and applies a framework to evaluate the potential for trans-boundary cooperation in water resource development/sharing with an application to Israel and its neighbors. This paper also discusses the possibilities for improving domestic water allocation both among regions and sectors. The benefits from partial domestic price equalization are apparently greater than the benefits of international cooperation but are blocked by other national objectives. However, international water projects may be instrumental in facilitating domestic price equalization because the costs of price equalization to losers are reduced when the two measures are undertaken in conjunction. Conversely, when prices are partially equalized as international projects are undertaken, the value of international projects is higher. With these considerations, new water projects and new prospects for peace in the region can potentially break existing coalitions behind current water pricing schemes.
